Is it possible to perform an action similar to "View Package Contents" on an IPA file? Here's why I ask... I love Mahjong, but hate most of the default "character" and number based tile sets. So, I normally make my own. This is usually pretty trivial with most Mahjong games on the Mac. It generally amounts to viewing the package contents, finding the resource(s) for the tile art, and modifying it appropriately. I'd love to be able to do this for one (maybe several) of the Mahjong games on the iPhone. I'm imagining an IPA is really just a collection of files, similar to any Mac app. Am I correct? Unfortunately, I'm on a PC at work currently and can't verify this for myself. I will say though, I sure can't find a way to "open" one up in Windows.
